Most interesting statement out of that Forbes newsletter I just got was: "Fracking requires between 4,000 m(3) and over 22,000 m(3) (25,000 bbl to 140,000 bbl) of water per well and produces toxin-laced brine that can be more than six times as salty as the sea. Its growth has energized the water industry, inspiring a bumper crop of new water treatment startups vying to treat the highly challenging flowback water."
A 50,000 bbl per day doesn't hold all that much in well # terms.
